So even if we can agree it wasn't actually aerobatic flight, even if we can agree it was within the aircraft operating limits, and even if we can agree it was smoothly executed, that still leaves the fact that the approach to the cliff and the subsequent maneuvering left little or no options for an escape path should anything decide to fail at that point. That's obviously fine for this pilot, but I prefer to have somewhere else to go on the day, rather than straight to the fireball.
